United States Patent 3 487,981 CONTAINER COVEli WITH SAFETY CLOSURE Charles F. Staples, 4456 Samoset Ave., Royal Oak, Mich. 48072 Filed Nov. 21, 1967, Ser. No. 684,725 Int. Cl. B6711 3/00 US. Cl. 222471 2 Claims ABSTRACT OF THE DISCLOSURE A container cover or top wall having a safety valve and air vent of the self-closing pinch-type for containers used for holding flowable materials and/or liquids; including such as flour-watergasoline--paint--soft drinks-fuel oil-inklubricating oil--syrupclay slipetc.

This invention relates to liquid and/or fiowable ma terial container covers with safety closures normally held in a closed position to prevent liquids or material from spilling or leaking therefrom and to prevent foreign matter entering into the container; also a cover containing a pouring spout and an air vent, both of which may be opened during a pouring operation and in which both spout and air vent are closed and are kept closed when not in use.

It is a common and accepted practice for homeowners and painters to purchase house paint in one gallon cans and after prying the cover ofl, to pour the paint into a smaller can for using. No pouring spout is provided and the paint is easily spilled and will often run down the outside of the gallon can and is wasted.

An object of the invention is to provide a container cover and valve mechanism, also a pouring spout and an air vent that will control the flow of material such as paint when the paint is being dispensed from one container to another container without spilling or loss of the paint. Material may be dispensed from the container without the use of any tools, also there are no loose parts.

Still a further object is to provide a container having at least one deformable pourting spout that may be compressed or pinched so as to make a closure and means for compressing a section of the pouring spout.

More specifically, it is an object to provide a container cover and valve arrangement to which the valves are maintained closed except when container is being filled or emptied.

It is a general object of this invention to provide a sanitary valve and air vent that are secured in a sealing relation with bulk liquid in container.

Further objects, features, and advantages of this invention will become apparent from a consideration of the following description, the appended claims, and the accompanying drawing in which:

FIGURE 1 is a top plan view embodying the present invention.

FIGURE 2 is a cross-sectional view of the assembly on line 11 of FIG. 1.

FIGURE 3 is a side elevation view of FIG. 1.

FIGURE 4 is a fragmentary sectional view on line 2--2 of FIG. 1.

FIGURE 5 is a fragmentary sectional view on line 3-3 of FIG. 1 and illustrates a valve held in the open position.

Referring to the drawings, specifically to FIG. 1, it will be seen that one embodiment of this invention may inice shown held in its lower position by spring 14, which in turn is located by shoulder pins 15 and 16, the shoulder pin 16, extends thru an aperture in operating handle 12, and is slotted 17, for receiving valve levers 22.

Shown at approximately to handle 11, are two pinch-type valves shown in closed position, and are held in closed position by pressure of spring 14.

The valve mechanism is comprised of a flexible tube 18, extending thru apertures in cover 10. A tube engageing and pinching element 19, mounted on cover 10, by rivets 23. A movable tube-engaging and pinching element 21 is formed with levers 22 and 25 so as to allow the members to pivot about pin 24 as a unit. Tube-engaging and pinching elements are shown in open position 22a by dotted lines.

In operation the cover and valve assembly are secured to the open end of a container by a pressfit of cover 10, over the outside diameter of a container, or, cover 10 may be secured by means of clamps, etc. Handle 11, is used for carrying the container and valve assembly. For pouring contents from the container, handle 12, FIG. 2, is raised upward. This action will move lever 22, and 25, to the open position 22a, shown by dotted lines FIG. 3. Thus material held in a container may be poured out with ease and without loss of material.

Various changes may be made in the details, arrangement and proportions of the parts without departing from the scope of my invention.

I claim:

1. In a cover and dual safety pinch-type valves, for a container for fiowable materials, flexible tubes upstanding thru apertures in said cover, a fixed valve member mounted on said cover, a movable valve member in pinching relation to said fixed valve member, means for retaining said fixed valve member and said movable valve member in pinching relation during the time that valves are not in use, a handle operably associated with said means and said movable valve member for moving said movable valve member away from pinching relation and a carrying handle mounted on said cover.

2. In a container cover and safety valve, said cover adaptable to the open end of a container for fiowable material, a flexible tube upstanding thru an aperture in said cover, a fixed valve member mounted on said cover, a movable valve member in pinching relation to said fixed valve member, for closing said valve, and means to maintain said valve in a closed position; a handle operably associated with said means and said movable valve member for moving said movable valve member away from said fixed valve member, thus opening said valve and a carrying handle mounted on said cover.
